Check out this full size roller coaster ride on the RGS. Imagine riding a
Goose down these tracks!

Better yet, do it now!

Get in the Cab of this Cadrail 3d drawing and experience the RGS as you have
never seen before. You will see why I call it a roller coaster. Otto Mears
as his best. Watch the animations (at right) at least.

Here is a 1 to 100 3d scale model (with HO tracks and Buildings) of the famous Ophir Loop
on the Rio Grande Southern.

The drawing
showcases the Terrain and Auto-Embankment features in Cadrail.
